Hi Cathy,

Conflict is an action word. It means "you may not do X because." "We
designate the null set for return to IANA" does not conflict with
2009-3. It renders 2009-3 functionally inert but it does not
"conflict." If there is any doubt about that, then it is appropriate
for us to clear up that doubt.

"We designate the null set for return to IANA" does not conflict with
ARIN practice either. It _changes_ ARIN practice. Generally speaking,
that's what policy is for.

If this is a case of poorly chosen words, I'll be pleased to withdraw
prop 135 once staff updates it's guidance to reflect that while 131
designates a null set for return under 2009-3, it does not _conflict_
with any active or tentative obligations under 2009-3 or any other
